Interesting idea! I'm not sure what I was doing wrong, since I could only get about 5 levels in at most. I couldn't figure out why the game would fail me. Sometimes I would fail while the ball was on the way to the next cog.
Keep making games!
Can you tell me what your browser and screen resolution is? Maybe it’s something about it.
I was using chrome in a laptop resolution, so 1900 x 1200.
